    Hey

    During my plugin execution I am calculating the vertexpoints for a given heigth point, refining a octahedron (link to image) to a final object (link to image)

    After executing the plugin, the viewport is not beeing refreshed until the calculation has been completed.
    For the next step in my plugin I need a redraw while this mesh is build up. Is this possible ?

    Cheers
    Sascha

    What kind of plugin did you finally choose, generator. tag etc?

    Usally you have to send MSG_UPDATE message to the object and call the EventAdd() function.

    cheers,

    Hey Matthias,
    I finally chose a command plugin. Within the execute I am allocating camera, target null object and my polyObject, adding them to the doc and calling several functions creating a height field, adding recursivly the new vertices and building a triangle strip (the polyobject)

    Cheers

    I have tried a few things with several update messages at serveral position inside my code. I don't recognize a visual update, but a higher calculation time. It seems, that, within a CommanPlugin, an editor view update is not an easy task. I am no pro, but i assume, a CommandPlugin does not use a cache like an ObjectPlugin does? The function GetVirtualObject() is called continously in an ObjectPlugin, but otoh making it difficult to bring more than one object into the document...

    Well I think, since a CommandPlugin is non-threaded, it seems, my object wouldn't be updatable during the calculation process...

    It is important that you call DrawViews(). Little example

    Hey Matthias,

    Thanks for this hint.

    HOLY MOTHER MARY GOD ! Is works in some way... but it runs soooooooo damn slow... Its better not to draw every polygon connected ^^

    [Edit]
    Yeah, every 100th or every 150th polygon is good deal

    Cheers
